Be it known that I, DAVID W. BRooKs; a'" citizen of the United States ofAmerica, residingin New York city, borough of Manhattan, and the StateofNew York, have in vented an Improvement in Facing-Bars for ConcreteStructures, of which the following description, in connection withthe-accompanying drawings, is a specification, like letters on thedrawings representing like parts. i T i The present invention relates toimprove ments in facing bars for use with concrete, these bars beingdesigned to protect the corners of concrete structures and othersurfaces thereof ordinarily subject to 'wear. The object is to provide acovering for the edge or other wearing surface which will effectuallyprevent abrasion and will further protect the concrete from fracture bytransmittingthe impact of possible shocks into the body of the mass. Afurther object is to utilize the entire contents of iron bars of uniformor standard width to the utmost advantage in providing anchoragefacilities, or, in other words, so that facing bars having anchoringextensions of different lengths may be stamped from bars of the samewidth and thickness.

The above mentioned objects of this invention are accomplished byproviding in such a bar a plurality of projections displaced atintervals from material along its edge to form anchoring members, thereach of the said anchoring members being determined by their distancesapart, as will be more readily understood from the drawings in whichFigure 1 is a perspective view showing a bar with its anchoring membersin different stages of formation.

Fig. 2 shows in cross section the application of a bar to corners of aconcrete structure, and, 3

Fig. 3 shows in perspective a similar construction wherein anchoringmembers are I formed on both longitudinal edges of the bar.

In Fig. 1 of the drawings, a typical facing bar is shown with anchoringmembers in the positions, a, b and 0 to illustrate different stages inthe formation thereof. The com leted anchoring member 0 comprises preerably a shank portion 1 having its base near the crest 6 of the bar anda headed por specifica'ti on of Iitters Patent. u iApplica tion filedDecember 19, 1913. fseriaisoasre.

prongs which may serve as compression members acting upon the concretelying between them to resist forces tending to move the bar outwardly.In forming such a member, it is stamped out of material forming theflange 4 of an ordinary angle iron or other iron of suitable crosssectional contour and thickness. The length of extension suitable forany given purpose is determined by the length of the strip 5 of materialcut from the edge of thefiange 4:. In this particular embodiment of theinvention the prongs are formed by bending this strip into any suitableshape, as indicated at b, and then the whole anchoring member may bedisplaced from the plane of flange 4 bypressing it inwardly as at 0.From the foregoing it will be obvious that the length of the extensiondepends upon the distance between the members a, b and 0, assuming thatall the material in the bar is made use of. Shoulders 7 are formed atthe base of each extension and the shank 1 may be provided with lateralprojections as 8 to give the face tending to prevent the bar fromshifting in the plane of its perforated flange.

It is contemplated that the parts herein described may be varied inlength and shape without departing from the spirit of the invention, as,for example, the length of the extensions in any given anchoring membermay be difierent or they may be bent into dissimilar shapes. And it isalso conceivable that the shape of the shank por tion may be varied fromthat herein described and illustrated, the essence of the inventionbeing the provision, in a suitable metal bar, of i a plurality ofanchoring members formed from the material thereof in such a way thattheir inwardly projecting extremities may be struck from materialforming the edge of the said bar, varying lengths of the same beingproduced by varying the distance between the said anchoring members.

I claim as my invention A facing bar for concrete structures, comprisinga facing member of substantially an gle iron form having punched-outportions at intervals along either or both webs, and anchoring. membersprojecting inwardly froin'the facing member,one opposite each opening inthe facing member, each of said anchoring members comprising a shank integral with the facing member and a pair of prongs diverging from theshank, the;

combine lengths of the two adjacent prongs 10 of any two adjacentanchoring meinbersbename to this specification, in the presence of 15two subscribing wltnesses.
